I've got the exact same setup and this seems strange. I don't think its the MSD as that shouldn't affect the voltmeter, and I think they actually operate down to 9V.
Bad earth somewhere? I would check the earths and MSD +12V first. Or maybe the battery is on its way out- does it crank readily or is it getting tired?
